Muirhead family from Scotland to Canada in 1854

Re: Muirhead family from Scotland to Canada in 1854

I am the granddaughter of one of Peters brothers. I know they came to Ontario and there were 6 more children born and registered in Keene. They came to the US to Tama County Iowa and Peters father Daniel became a naturalized citizen in 1876. Peter married Hattie Gilford Baker in 1889 and had 4 children. He died in 1944 at the age of 90. My mother is named after Jessie Scott. The family tree is on ancestry.com placed by a granddaughter of Peters.
